Arabic text is revering lines in reportlab

In reportLab, I need to display an arabic paragraph. I am using arabic-resharper and bidi-algorithm. The problem appears in the algorithm that reverses lines.

My code is:

def format_arabic_paragraph(arabic_text: str, paragraph_style: ParagraphStyle):
        reshaped_text = arabic_reshaper.reshape(arabic_text)
        bidirectional_text = algorithm.get_display(reshaped_text)
        formatted_paragraph = Paragraph(bidirectional_text, paragraph_style)
        return formatted_paragraph

arabic_text='وحدة1 وحدة2'

Here's the output:<br>
وحدة2<br>
وحدة1

Here's what I expected:<br>
وحدة1<br>
وحدة2

Reportlab has partial bidirectional support using Fribidi. It is disabled by default. There is an option rtlSupport in reportlab/rl_settings. See user guide section on site configuration. In my installation, I added a file ~/.reportlab_settings and added the line rtlSupport=1.

In ParagraphStyle() set wordWrap="RTL".

An example:

from reportlab.platypus import Paragraph
from reportlab.lib.enums import TA_RIGHT
from reportlab.pdfbase import pdfmetrics
from reportlab.pdfbase.ttfonts import TTFont
from reportlab.lib.pagesizes import LETTER
from reportlab.lib.styles import ParagraphStyle, getSampleStyleSheet
from reportlab.platypus.doctemplate import SimpleDocTemplate

pdfmetrics.registerFont(TTFont("Arial Unicode", "Arial Unicode.ttf"))

arabic_text='وحدة1 وحدة2'

doc = SimpleDocTemplate(
    "repro_ar.pdf",
    pagesize=LETTER,
    rightMargin=280,
    leftMargin=280,
    topMargin=72,
    bottomMargin=72,
)
styles = getSampleStyleSheet()
normal_arabic = ParagraphStyle(
    parent=styles["Normal"],
    name="NormalArabic",
    wordWrap="RTL",
    alignment=TA_RIGHT,
    fontName="Arial Unicode",
    fontSize=14,
    leading=16
)

flowables = [Paragraph(arabic_text, normal_arabic)]
doc.build(flowables)

This gives me:
